Chronometer & Superlative Chronometer

Post by tempusmaximus »

What is the difference between a chronometer and a superlative chronometer ?

Since 1973 the Controle Officiel Suisse Des Chronometers C.O.S.C has been the gold standard in watch precision certification , but some brands add more stringent requirements to their already COSC certified line up .
